Overpower

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 8945HX is a 16-core, 32-thread mobile processor based on the Zen 4 architecture (Dragon Range codename), built on a 5 nm process at TSMC. It has a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a 55 W TDP. The CPU's cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 64 MB of L3 cache. Memory support is dual-channel DDR5 with a bandwidth of 83.2 GB/s, and the chip connects via PCIe Gen 5 with 28 lanes.

Benchmark results place this CPU in the 95th percentile among all processors, which is an exceptionally strong showing. Its average benchmark score is 76,212, and the nearest rival comparison underscores how tight the competition is at the top. The Intel Core Ultra 9 285HX scores 76,155, which is a 0.1% delta from the 8945HX — essentially a statistical tie. The AMD EPYC Embedded 8224P sits at 76,492 (-0.4%), the AMD Ryzen Threadripper PRO 9945WX at 76,513 (-0.4%), and the AMD Ryzen 9 9950X3D at 75,779 (+0.6%). In practical terms, the 8945HX is delivering flagship-tier multi-threaded performance that rivals desktop-class parts.

Looking at specific synthetic workloads, the Cinebench R23 multi-core score of 42,713 and single-core score of 6,030 both reflect strong execution. The PassMark multi-thread score of 51,405 and single-thread score of 3,907 further confirm balanced performance across both lightly-threaded and heavily-threaded tasks. For a game like Overpower, which is an action title released in August 2023, the CPU's capability is far beyond what the measured frame rates would suggest as a bottleneck. The data shows that even at 1080p Low settings, where the CPU would typically be most stressed, the average FPS reaches 64 — a figure that would not tax a 16-core/32-thread processor with this much cache and bandwidth.

The CPU's 64 MB of L3 cache is particularly relevant for gaming, as it allows for more data to be held on-die, reducing the need to pull from system memory. The 83.2 GB/s memory bandwidth is also ample for feeding both the CPU and the integrated GPU in this combo. Given that the CPU's nearest rivals are all within 0.6% of its average score, the data indicates that this processor is not the limiting factor in Overpower's performance. The frame rates observed across all resolutions and settings are constrained by the GPU, not by CPU throughput or latency.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon 890M is an integrated graphics processor based on the RDNA 3.5 architecture, using the Strix Point chip on a 4 nm process at TSMC. It has a base clock of 400 MHz and a boost clock of 2900 MHz, with a TDP of just 15 W. The GPU's memory is "System Shared," meaning it draws from the same DDR5 pool as the CPU, with bandwidth listed as "System Dependent." This is a critical detail: the 890M has no dedicated VRAM, so its performance is tied directly to the system's memory configuration and the CPU's ability to feed it data.

The GPU features 1,024 shading units, 64 texture mapping units, 32 ROPs, and 16 ray tracing cores. It delivers a pixel rate of 92.80 GPixel/s and a texture rate of 185.6 GTexel/s. Floating point performance is rated at 5.939 TFLOPS for both FP32 and FP16 (1:1 ratio). The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and connects via PCIe 4.0 x8.

In terms of benchmark standing, the Radeon 890M sits in the 45th percentile among all GPUs, with an average score of 9,210. Its nearest rivals are telling: the AMD Radeon Vega 8 scores 9,221 (-0.1% delta), the NVIDIA GeForce GTX 960 scores 9,273 (-0.7%), the NVIDIA GeForce GTX 465 scores 9,294 (-0.9%), and the NVIDIA GeForce GTX 850M scores 9,302 (-1%). These are all older discrete GPUs, which suggests the 890M is performing at a level roughly equivalent to a mid-range discrete card from several generations ago. That positioning is consistent with the measured FPS in Overpower, where the GPU is clearly the limiting factor.

The 3DMark Steel Nomad DX12 score of 590 and Geekbench OpenCL score of 37,254 both indicate modest graphics throughput. The PassMark G3D score of 8,076 and GPU compute score of 4,157 further show that while the 890M is capable, it lacks the raw power to push high frame rates in demanding action titles at higher resolutions. The fact that the GPU has no dedicated VRAM and relies on system memory means that as resolution increases, the memory bandwidth becomes a shared resource, likely exacerbating performance drops.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals a clear pattern of GPU-bound scaling. Starting at 1920x1080 with Low settings, the average FPS is 64. Moving to 2560x1440 at Low, the average drops to 57, a reduction of 7 FPS (about 10.9%). At 3840x2160 with Low settings, the average falls to 48, which is 16 FPS below the 1080p figure (a 25% drop from 1080p to 4K). This scaling is relatively moderate, suggesting that at Low settings, the GPU is still managing to keep up with the resolution increase without catastrophic losses.

At Medium settings, the pattern is similar but with lower absolute numbers. At 1080p, the average is 40 FPS. At 1440p, it drops to 36 FPS (a 10% reduction). At 4K, it falls to 30 FPS (a 25% drop from 1080p). The High settings show a slightly steeper proportional decline: 37 FPS at 1080p, 33 FPS at 1440p (an 10.8% drop), and 28 FPS at 4K (a 24.3% drop from 1080p). Ultra settings follow a similar trajectory: 31 FPS at 1080p, 27 FPS at 1440p (a 12.9% drop), and 23 FPS at 4K (a 25.8% drop from 1080p).

The consistency of the percentage drops across settings — roughly 10-13% from 1080p to 1440p and 24-26% from 1080p to 4K — strongly indicates that the GPU is the primary constraint. If the CPU were the bottleneck, the FPS would remain relatively flat across resolutions, as the CPU workload does not scale with resolution. Instead, the data shows that each resolution step incurs a predictable performance penalty, which is characteristic of a GPU-limited scenario. The Radeon 890M's shared memory architecture likely amplifies this effect at 4K, where the demand for texture data and memory bandwidth increases significantly.

The fact that even at 1080p Low, the average FPS is only 64, and at 1080p Ultra it drops to 31, further confirms that the GPU is the limiting component. A CPU with this much headroom would easily push well over 100 FPS in most action titles if given a more powerful GPU. The data here tells a consistent story: the Ryzen 9 8945HX has ample compute power, but the Radeon 890M's integrated nature caps overall performance.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured frame rates for Overpower on this combo are provided across three resolutions and four settings presets. Here is the full breakdown:

1920x1080 (Full HD):

• Low: average 64 FPS
• Medium: average 40 FPS, with a minimum of 34 FPS and a maximum of 46 FPS
• High: average 37 FPS
• Ultra: average 31 FPS

2560x1440 (Quad HD):

• Low: average 57 FPS
• Medium: average 36 FPS, with a minimum of 30 FPS and a maximum of 41 FPS
• High: average 33 FPS
• Ultra: average 27 FPS

3840x2160 (4K Ultra HD):

• Low: average 48 FPS
• Medium: average 30 FPS, with a minimum of 26 FPS and a maximum of 35 FPS
• High: average 28 FPS
• Ultra: average 23 FPS

The data shows a clear hierarchy: at any given resolution, Low settings deliver the highest frame rates, followed by Medium, then High, with Ultra being the most demanding. The gap between Low and Medium is substantial — at 1080p, the difference is 24 FPS (64 vs. 40), which represents a 37.5% drop. At 1440p, the gap is 21 FPS (57 vs. 36), a 36.8% drop. At 4K, the gap narrows to 18 FPS (48 vs. 30), a 37.5% drop. This consistent proportional drop suggests that the Medium preset introduces a significant additional GPU load compared to Low.

The step from Medium to High is much smaller. At 1080p, it's only 3 FPS (40 to 37). At 1440p, it's also 3 FPS (36 to 33). At 4K, it's 2 FPS (30 to 28). The step from High to Ultra is similarly modest: 6 FPS at 1080p (37 to 31), 6 FPS at 1440p (33 to 27), and 5 FPS at 4K (28 to 23). This pattern indicates that the visual quality gains from Medium to High to Ultra come at a relatively low frame rate cost, but the jump from Low to Medium is where the most significant performance hit occurs.

The minimum FPS figures for Medium settings (34 at 1080p, 30 at 1440p, 26 at 4K) suggest that frame pacing remains stable, with no severe dips below the average. The maximum FPS values (46 at 1080p, 41 at 1440p, 35 at 4K) show that there is some headroom in less demanding scenes, but not enough to achieve a consistently smooth experience at higher settings. The combo ranks 2,804 out of 2,980 total combos in this game, placing it near the bottom 6% of all configurations tested.

Its nearest rival, the Intel Core Ultra 9 285HX, is only 0.1% different in average score, indicating top-tier performance. The frame rates in Overpower are limited by the GPU, not the CPU.

Q: How does the AMD Radeon 890M compare to its closest GPU rivals?

A: The 890M has an average benchmark score of 9,210, which places it at the 45th percentile. It is within 1% of the AMD Radeon Vega 8 (9,221), NVIDIA GeForce GTX 960 (9,273), NVIDIA GeForce GTX 465 (9,294), and NVIDIA GeForce GTX 850M (9,302). This means it performs similarly to older discrete GPUs from the GTX 900 and 800 series.

Q: What is the best resolution for playing Overpower on this system?

A: At 1080p with Low settings, the average FPS is 64, which is the highest measured in the data. At 1440p Low, it drops to 57, and at 4K Low, it falls to 48. Lower resolutions provide the most headroom for smoother gameplay, while 4K is only playable at Low settings with 48 FPS.

Q: Why does the FPS drop so much when going from Low to Medium settings?

A: The data shows a consistent 37% drop in average FPS from Low to Medium across all resolutions. At 1080p, it goes from 64 to 40 FPS; at 1440p, from 57 to 36; at 4K, from 48 to 30. This suggests that the Medium preset introduces a significant increase in GPU workload compared to Low, making it the most impactful settings change in terms of performance.

Q: Can this system handle 4K gaming in Overpower?

A: At 4K, the highest average FPS is 48 on Low settings, dropping to 30 on Medium, 28 on High, and 23 on Ultra. While 48 FPS at Low is playable, the experience degrades rapidly as settings increase. For a smoother 4K experience, staying at Low settings is the only viable option.

Q: Does the lack of dedicated VRAM affect the Radeon 890M's performance?

A: The GPU's memory is listed as "System Shared," with bandwidth described as "System Dependent." This means it relies on the same DDR5 memory as the CPU. The measured frame rates at 4K (48 FPS max at Low) indicate that higher resolutions, which demand more memory bandwidth, cause significant performance drops, consistent with the shared memory architecture being a limiting factor.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and the desired frame rate. For the best overall experience, the Low preset at 1080p delivers the highest average FPS of 64, which provides the smoothest gameplay. This is the only configuration in the entire dataset that approaches a 60 FPS average, making it the clear choice for players who prioritize fluidity over visual fidelity.

At 1440p, the Low preset yields 57 FPS, which is still respectable but below the 60 FPS threshold. The Medium preset at 1440p drops to 36 FPS, which is a significant decline. Given the data, 1440p Low is the most balanced option for this resolution, offering a playable frame rate without the severe performance hit of higher presets.

At 4K, the Low preset achieves 48 FPS, which is the only setting that produces a comfortable gaming experience. The Medium preset at 4K drops to 30 FPS, and Ultra falls to 23 FPS, both of which are below the generally accepted playable threshold. For 4K users, sticking with Low settings is the only viable path to a satisfactory experience.

The data indicates that the Medium, High, and Ultra presets offer diminishing returns relative to their FPS cost. The step from Low to Medium costs roughly 37% of the frame rate, while the steps from Medium to High and High to Ultra each cost only 5-6 FPS at 1080p. This suggests that if a player can tolerate the drop from Low to Medium, they might as well push to High or Ultra for the extra visual quality, as the additional cost is relatively small. However, given that even at 1080p Medium the FPS is only 40, the Low preset remains the recommended choice for maximizing performance.

The combo's rank of 2,804 out of 2,980 in this game reinforces that this configuration is not designed for high-fidelity gaming. The strongest recommendation from the measured data is to use the Low preset at 1080p for the best frame rate, with 1440p Low as a reasonable alternative if higher resolution is preferred. 4K is only playable at Low settings, and even then, the 48 FPS average leaves little margin for demanding scenes.
